12 He said, "You are responsible for the Levitical families; now consecrate yourselves, both you and your relatives, and bring up the Chest of the God of Israel to the place I have set aside for it. 13 The first time we did this, you Levites did not carry it properly, and God exploded in anger at us because we didn't make proper preparation and follow instructions." 14 So the priests and Levites consecrated themselves to bring up the Chest of the God of Israel. 15 The Levites carried the Chest of God exactly as Moses, instructed by God, commanded - carried it with poles on their shoulders, careful not to touch it with their hands. 16 David ordered the heads of the Levites to assign their relatives to sing in the choir, accompanied by a well-equipped marching band, and fill the air with joyful sound.
